Patent CA-2217079-C (CA)
Title: Articulation assembly for surgical instruments
Inventor: NALAGATLA ANIL K
IPC: A61B19/00
Filed: 1997-09-26
Granted: 2006-04-25
Abstract: An articulating surgical instrument which has an articulation transmission assembly for remotely articulating an end effector of the instrument is disclosed. Ratcheting rotation of a compressible deck within a detent housing of the assembly from a first locked position to a second locked position causes axial movement of an elongated transmission member for the articulation of the end effector from a first position to a second position angled from the first position. Also disclosed is a flexible neck assembly for articulating the end effector of the surgical instrument.  Neck ribs, each having an interior plate and an exterior dish, extend from a central longitudinal rib separating a pair of flexible neck portions of the assembly. A pair of transmission band assemblies, each having an interior articulation band and an attached exterior reinforcement band, reciprocate in opposite directions within side slots of the neck ribs in response to actuation of the articulation transmission assembly.  Reciprocation causes the flexible neck assembly to bend, effecting articulation. The shape of the neck ribs optimizes the radius of curvature when articulation is effected, and the reinforcement bands prevent buckling of the articulation bands.

Title: Notched end hitch bar
Inventor: KRAGER JON L
IPC: B60D1/14
Filed: 1997-10-22
Granted: 2006-05-30
Abstract: A hitch bar for a trailer hitch assembly is formed from an elongated bar including a notched proximal end and a mounting rack carried on the distal end. The notch is V-shaped and extends in a vertical plane so as to define upper and lower projecting lugs at the proximal end of the bar. The notch reduces the stiffness of the elongated bar at its proximal end allowing the bar to deflect and absorb a portion of the reaction load. The bar also redistributes that load in the hitch box, thereby reducing localized force and extending the life expectancy of the hitch.

Granted: 2004-06-29
Abstract: The window unit of the invention comprises four peripheral channel members linked with comer members to form a window frame. Two glass panels are spaced by this frame to form an inner chamber, the venetian blind structure of the invention being located completely therein. The venetian blind structure comprises a plurality of horizontal slats pivotally supported at both their extremities and each having an integral toothed wheel engaging a complementary rack on an actuator bar, the latter positioned adjacent to a side peripheral channel member and being free to move upwards or downwards along it. This upward or downward movement imparts a pivoting movement to the slats. The venetian blind structure further comprises a support channel member supporting a reversible electrical motor having a driving shaft. This shaft is aligned to engage properly the actuator bar.      When the driving shaft rotates, it imparts a linear upward or downward movement to the actuator bar, thus pivoting the slats consequently. The alignment of the shaftis done by means of an L-shaped plate bored and threadingly engaged by an alignement sleeve, the latter being coaxially engaged by the driving shaft. This alignment of the shaft prevents the parts of the venetian blind structure from moving in undesired directions, relative to one another, and therefore reduces the chances of breaking these parts.

Title: Counter-rotating scanner
Inventor: STANFIELD JAMES M
IPC: G06K7/10
Filed: 1997-10-06
Granted: 2006-08-01
Abstract: A scanner and a method for scanning a beam along a path employ a housing (320) that defines a first cylindrical cavity (322). A ring gear (330) is disposed within the cylindrical cavity and affixed to the housing.     A beam (312) is generated from a fixed location relative to the housing. A drive disk (340) is disposed within the first cylindrical cavity. The drive disk defines a second cylindrical cavity (348) and has a first axis of rotation (315). The drive disk defines a first channel in communication with the beam. The first channel (346) has a first proximal end pivotally rotatable about an axis adjacent the fixed location. A scan disk is disposed within the second cylindrical cavity and has a second axis of rotation offset from the first axis of rotation. The scan disk defines a second channel (366). The second channel has a second proximal end (374) in communication with the first distal opening (354). A spur gear (332), affixed to the scan disk, engages the ring so that the drive disk rotates in the first direction, the spur gear is displaced along the ring gear (330), thus causing the scan disk to rotate in a second direction opposite the first direction causing the second distal end to reciprocate. The beam is coupled through the first channel and the second channel and out of the second distal opening toward the path, thereby causing the beam to scan along the path as the second distal end reciprocates.

Abstract: An inline component for a liner assembly, usable particularly in deviated wellbores, is disclosed. The component involves a series of offset passages to create sufficient turbulence in the circulating cement during a cementing job so as to eliminate the phenomenon of roping where there is inefficient displacement of mud with the circulating cement. The multi-component inline device has peripheral seals to prevent leakpaths along the inside wall of the casing being cemented. The offset flow passages are presented in individualized components which are rotationally locked to each other and have peripheral sealing devices. The stack of components is retained within the casing to prevent its longitudinal movement during the pumping of cement.   The preferred materials are soft metallics which facilitate drilling out if required. The interlocking nature of the components also eliminates relative rotation to facilitate drill-out.
